Answer:
y = 3x - 5
Step-by-step explanation:
y = 3x + 4....the slope here is 3. A parallel line will have the same slope.
y = mx + b
slope(m) = 3
(4,7)...x = 4 and y = 7
now we sub and find b, the y int
7 = 4(3) + b
7 = 12 + b
7 - 12 = b
- 5 = b
so ur equation is : y = 3x - 5 <===
Answer:
D
Step-by-step explanation:
(f-g)(x) = f(x) - g(x)
=3x^3+8x^2-7x-4-(2x-6)
=3x^3+8x^2-9x+2
Answer:
Answer 2/B
Step-by-step explanation:
The one with Parentheses
-(log6 x-4)
Let
x---------> radius of the cylinder
y---------> the height of the cylinder
we know that
x=2y
[surface area of cylinder]=2*[pi*r²]+2*pi*r*h
surface area=108*pi m²
r=x
h=y
x=2y
108*pi=2*[pi*(2y)²]+2*pi*(2y)*y
108*pi=8*pi*y²+4*pi*y²
108*pi=12*pi*y²
y²=108/12
y²=9----------> y=√9--------> y=3 m
x=2y-------> x=2*3-----> x=6 m
the answer is
the height of the cylinder is 3 m
Answer:
The answer is D.
Step-by-step explanation:
When you subtract 9 from h, the word “then” is a key term that means it’s usually in parentheses. Then you divide three.
